Check your semaphors and your solaris setting but it does sound like you need
at least 3G of memory. I have 3G for this many connections on Windows.
Also MTS creates performance issues. Try to go with connection pooling on the
app end. IF .Net check for garbage collections ...Check to make sure the app
is closing connections, no leaks
In the meantime, see if you can lower large pool, java pool, open_cursors,
session cached cursors for a quick fix in the mean time.
Been there done that with windows... Having bad flash backs now.

Subject: SGA/PGA question
Hi,
We have 10.1.0.3 installed on sun solaris 10 having 2GB RAM and 2GB swap
file. In our system 4-5 application starts at same time and each
requires about 180 connections to the database. So about 900~ processes
can be connected at the same time and we have set the following
parameters:
Processes = 1000
Pga_target = 200MB
SGA_TARGET = 600MB
We are using the dedicated server model and getting following error
frequently and also notice that physical RAM drops to 0 MB free:
Ora-12500 (unable to start the dedicated process)
Since this is just a development box, so to fix this issue we are
planning to move to MTS model.
Is there any other way to solve this issue, if we have to go to the MTS
model what should be the value of PGA and SGA to be set?
Thanks
